Abstract

The invention relates to a sprocket assembly (16) for a bicycle rear wheel. The sprocket assembly (16) comprises at least eleven sprockets (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11). All of the sprockets (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11) of said sprocket assembly (16) have an overall axial bulk (M) lower than or equal to 46 mm.
